Solo female travel · Iran

Hi everyone, I’m really keen to visit Iran for three weeks in mid-March 2015. What worries me a bit isn’t so much traveling alone—I’m used to it and know the Middle East well—but rather the current events (Islamic State) that could potentially become dangerous. Flights are pretty cheap at the moment, and I’d like to book before prices go up.

Any advice from people who know the ground situation and Iranian current affairs better than I do would be much appreciated! :)
